Deer Hunter,
What I have done to make the lever easier to open is take the buttstock off. Next, you'll see the coil spring/plunger that moves the safety on when the lever is moved to open the barrels. If you carefully take some needlenose pliers or something that won't cause damage, you can pull back on the spring/plunger to the rear (it will be tight) and then pull it to the side and out of the receiver. Next, I take the plunger and grind off a little bit at a time on the end that would hit the safety mechanism. When it is put back together, the lever will be able to open up further since the part you ground off doesn't run into the safety as much. At least this worked on my guns. If you take off too much, the safety will only operate manually, since the full opening of the lever will not allow the plunger to engage it because of the part you ground down. I hope I made sense of this. If it's confusing, I'm going to take some pictures of mine and label everything and post it later this evening when I'm home from work. I'll also go more indepth on why this plunger that hits the lever to operate the safety will also possibly let the gun open up easier.
